Chemical pump in the use of mechanical seal to note

We all know that chemical pumps in the use of mechanical seal to pay attention to what matters? If you do not know, now we will introduce the chemical pump to use chemical mechanical seal should pay attention to matters. Chemical pump in the use of mechanical seal to note (1) general mechanical seal for clean, non-suspended particles in the media. Pipeline system installed and storage irrigation should be carefully washed to prevent solid impurities into the mechanical seal face seal failure. (2) in the crystallization of the medium, the use of mechanical seals, we should pay attention to regular flushing. (3) Demolition of mechanical seals should not be careful to use hand hammer, iron and other percussion, so as not to damage the dynamic and static sealing surface. (4) If the dirt can not be removed, do not force to remove, should try to remove dirt, rinse. (5) Before installing the mechanical seal, check all sealing elements for failure and damage, and replace if necessary. (6) should be strictly checked moving ring and stationary ring grinding seal face, does not allow any scratches, bump and other defects. (7) pay attention to deviations in the assembly, tighten the screws, should be evenly tightened to avoid deflection, the seal failure. (8) Correctly adjust the spring compression, so that it will not be too tight or too loose. (9) For the mechanical seal with external flushing, open the flushing fluid before starting to fill the sealed chamber with sealing liquid. When stopping, stop the seal first and then close the seal flushing fluid. The above is the chemical pump in the use of mechanical seals should pay attention to the matter, I hope the above content can be used in chemical pumps, play a reference role.
